.The present invention relatesto `gas separators, and aims to `provide ia novel andf improved gas separatingmeans particularly useful forincinerators for hilrning'arhage 5 and other refuse, this application.Qing a division ,of the application for patent on V1n- Lcinerators, ledOct. 7, 1925,!Serfal No. 60-

.9.6.0 (newV Patent No. 1,651,636, granted Dee. 6,1927);

It is the object of the irwentonY to provide novelV means for Separatingfrom the ,gas Y'which is discharged to thejiltlllosphere, the unburnedparticles, such as Contained in smoke and green gases,`in Order toprevent the gases discharged into the? atmosphere from being obnoxious.VThe unharmed material'or particles are arrested, thereby preventingexcessive soot andV obnoxious Y gases :from passing intotheatmosphere,"making the incinerator available for use in 'localitieswhich strictly require incinerators to burn without offensive smoke orsmell.

Withthe foregoing andother 'objects in lview, whichwill he apparentesthe deseri Y 25" tion proceeds, the` invention jre-Siders im econstruction and. arrangement of parte, asi", through the centralportion.ofthe flueway -hereinafter described and claimed, itfbeing understoodthat changes oanhernadewithin the scope of whatis claimed, without de-A, 30 parting from the spirit rof theinvention.Y

on which is disposed ltering material 90, which may be coke, cinders,soil, or other suitable material to arrest particles of soot, ashes andother solid material thatk enters the space 82.

The gases passing through the opening 76 from the furnace are separated,the valve or damper 78 being opened so that, in addition to the forceddraft created by air discharged through the nozzle 54, there is anatural draft up the smoke stack 75. The flames and more completeproducts of combustion travel along the center of thestream,

as is well known, and pass through the center v of the flue-Way leadingfrom the opening 7 6 to the opening 77, while the smoke and green fgases moving along the sides andtop of said flue-way'pass through theslots between the separators 79, 80 and 81 into the space 82. If thenatural draft is sufficient then the damper -84 maybe opened so that thenatural draft will draw the smoke and green gases upwardly through thebeds or layers 90 of filtering material whichwill Varrest'the particlesof soot and other solid matter. If the natural draft is not sufiicientfor this purpose,'then the fan 87 Vis operatedvtocreate a forced draftup throughthe layers`90 of filtering material, and the filtered gasisdischarged from either opening 83 or 85 into the smoke stack. In thisway,smoke and green gases are eliminated, so that'the gasesdischargingfrom the smoke stack will not constitute a nuisance or be obnoxious. Itwill be noted that the flue-way is tapered or decreases in size'from theopeningv76 tothe opening 77, thereby having a tendency to compress thegases flowing through said uexway', and the smoke and green gasesremaining at the outside ofthe stream iwill be crowdedvYthrought-heslots or openings between the separators 79, 80 and v81 intothe space 82.` The draft extending through the space 82 will servetodraw'the smoke and green gases from the separating means, so .as `notto impair the flow kof gases from the furnace to the smoke stack,inasmuch as the gases flowing through thespace 82 pass into :the smokestack through' the opening' 83 or to' through Ithe space 82 will assistin drawing the opening 85 and fan 87.' This draft the smoke and greengases from the vseparating means through the filtering material v90. Thefiltering beds yor layers 90 may beof any suitable area or extentnecessary, preferably greater than the cross-sectional area of the smokestack75, so as not to impair the draft, and the filtering material maybe removed and replaced as voften as necessary. `The housing 74 hasclean-out doors 91 in order that soot andgother accumulations may 'beremoved. g

Figs; 4`a`nd 5 illustrate variation in the means forl removing the smokeand green gases from the products of'combustion for fromthe chamber ofthe housing 74.

The heads 108 are enclosed within the covers105 which alsov close theopenings 101 The heads 103 are mount-ed for turning movement 'aboutvertic'alaxeaand supply pipes'lOA for steam, compressed air or otherpressure uid are connected by swivel connections with the upper ends ofthe heads 108 and have control valves 107. The lower ends of thejheads103 are geared, as at 108, to shafts 109 that have hand levers 110 whichmay be swung to turn the heads"103` and change the angular positions oftheV nozzles 104. The housing 74 'has the space 82 in which the grates89 are disposed to Asupport the filtering material, and a suction fan 87is located between the 'space 82 and smoke stack 75', the comico-- tionsof the space 82 with the smoke stack being the'same as shown in Fig. 1.c

The steam,'air or other fluid being Vdischarged under pressure from thenozzles 104 is directed obliquely across the stream ofl products ofcombustion passing through the passage 100, and the. streams of fluidfrom the nozzles passing through the openings 102 will intercept theparticles of soot, thereby blowing the smoke and green gases through theopenings 102 into the housing 74 so that the smoke and green gases willbe filtered before passing through the smoke stack. yThe 'angularpositions ofthe nozzles 104 may .be adjusted according to the velocityof vthe products 'of combustion in flowing through :the passage 100. Itwill be apparent that thefluidV discharged from the nozzles fromone'side Vof the passage 100 will have a tendency to force the smoke andgreen gases toward the opposite side of the passage so as to passreadily through the openings 102, thereby separating such smoke andgreen vgases from the products of combustion which pass through stack- Y1 Having thus described the invention, what 'isclaimed as new is j1. Agas separator comprisingafluewaydecreasing in size from its inlet to itsoutlet, a`

2. A gas separator including a lueway, a chamber at least partlysurrounding said flue- Way, said iiueway having a series of openingsbetween its ends for the ilow into said chamber ofthe products ofcombustion which move along the outside of the stream vpassing `throughsaid flueway, and means for creating avforced draft from saidiueway'through said openings and chamber.
